\ LUBRIOATING SYSTEM.

Specification of Letters ratent.

Patented Feb. 24, 1920.

Original application flied November 4. 1916. Serial No 129,540. Divided and this application filed February 14, 1918. Serial No. 217,287.

To all whom it may concern:

ie it known that I, Jonx O. Hnrszn, a citizen of the. Inited States, residing at Lowell, Middlesex county, and State of Massachusetts, have invented and discovered certain new and useful lmm-ovements in Labricating Systems, of which the following is a specification.

My invention relates to a lubricating system for internal combustion engines and consists in the combinati ns and arrange ments of elements hereinafter described and particularly set forth in the accompanying' claims.

The invention has for its purpose to provide a lubricating system for a power plant or unit embodying a main engine aml an auxiliary engine which are operable simultancously or iiidcpcudenlly. and in which the auxiliary unit serves as a starting medium for the main engine. and the operation of the. auxiliary engine serves to circulate the lubricant at a uniform ilow to the main engine. the auxiliary engine. and to all workin; parts associated therewith. And wherein the said lubricant is constantly fed independently of any variation in the speed of the main engine.

The invention forms a division of the subject matter disclosed in my co-pendina applicati n for I. S. patent entitled Auxiliary power system for internal combustion enines. Serial No. llthfilti. and dated Novem- B01 4, nuts.

The invention is disclosed by way of illustration in the accompanyiup i rawinp, which shows a side clevational view of the main and auxiliary power units with the invention applied thereto.

Referring to the drawing. 1 is an internal combustion engine constituting the main motor. and H is an electric storage battery constituting one of the primary sources of energy of thc generating" set. and across the line of thc battery is an electromagnetic machine 7 which is adapted to serve either as a motor or asagencrator.the change from the one to the other function beinp automatically effected by the owl-balancing of counter electroanotive forces.

On the shaft of the motor gene -ator 7 is an internal combustion engine 8 of lesspower capacity than the main engine but of sufficient power to drive the generator, to

start the main engine and to drive the vehicle or other object at moderate speeds independently of the main engine.

The electromagnetic machine and the battery are of such capacity that when said machine is acting as a motor its capacity is not only sufficient to start. the auxiliary engine but also to add its power to that of the auxiliary either when the latter is runnin at low speed or at its maximum so as to ai in rotating the auxiliary engine shaft and thus assist in starting the main motor, or driving thedriven element ordinarily driven by said main motor.

The auxiliary engine is preferably adapted to operate continuously and when so op crating it has a fixed speed, and consequently drives the motor generator and the other parts to which it is connected at a uniform speed which is an important. factor in delivery current of constant amperage to the battery for recharpgirul purposes and also of advantage in connection with the utilization of the engine for driving other mechanisms, as compared to the usual system in which the mam engine is employed to recharge the battery and perform said other functions and in which arrangement the power delivered from said main engine varies. of course, with the variation of the speed thereof.

The elements described in the foregoing operate after the manner stated. and for a further description of said elements, their associate parts. and the manner of operation referem-c'-1u'ay be had to my co-pending application herein identified.

The. shaft 11. of the auxiliary engine has mounted thereon a pump 28 of the force feed lubricating system and which pump operates dircctl from the auxiliary engine. to force the lubricant to all parts of the main engine. the auxiliary engine. and all mechanism operated thereby.

pipe 29 delivers the oil from the crank casing 30 to the pump .28, and a pipe 31 delivers the oil from said pump '28 to the main bearing 32 of the crank shaft of the main engine. and from this point of delivery the lubricant will flow along the crank shaft for itscntire length after the well known manner aml by the system shown, the lubricant is distributed to all working parts.

The direct connection of the oil pump with the constantly running auxiliary engines uontinuous HlllJlll) ol lubriprnrhlw for n pnrls uutonnlturully,
